SUMMARY: Ultra 5 internal disk timeout and disappear during heavy I/O

I happily report the problem is resolved.

Many people think it is a disk problem, and advised me to run
the read analysis. I did but I did not find any errors.

Some say it is a "BIOS" (openboot) problem. Officially Sun supports
only 2x20GB internal disk drive for Ultra 5, and Sun uses Seagate.
But when Sun supported 1x9GB drive, I already used 2x17GB disk drives.

I resitted the cables, and upgraded the OBP to
"OBP 3.31.0 2001/07/25 20:36". I am so sure which action did the
trick, but I tend to believe it is the later.

I did Oracle import 5 times (each took 2.5 hours), and all of them
were successful.

I hope this info is of use for people who uses Ultra 5 and want to
use large capacity internal disks for testing and development.

Thanks all.
